Push the drive tray handle to the closed (locked) position.e. Check the hard disk drive status indicator to make sure that the hard diskdrive is operating correctly. (You might have to restart the server before thedrive is recognized.) If the amber hard disk drive status LED for a drive is litcontinuously, it indicates that the drive is faulty and must be replaced. If theamber hard disk drive status LED for a drive is flashing slowly, this indicatesthat the drive is being rebuilt. If the amber hard disk drive status LED for adrive is flashing rapidly, this indicates that the controller is identifying thedrive. If the green hard disk drive activity LED is flashing, it indicates thatthe drive is in use.Note: If the server is configured for RAID operation using an optionalServeRAID adapter, you might have to reconfigure your disk arrays afterinstalling hard disk drives. See the ServeRAID documentation on the IBMServeRAID Support CD for additional information about RAID operation andcomplete instructions for using ServeRAID Manager.8. If you are installing additional hot-swap hard disk drives, do so now.If you have other options to install or remove, do so now; otherwise go to“Completing the installation” on page 68.IDs for hot-swap hard disk drivesHot-swap server models have drive bays that are connected to a SAS/SATAbackplane. This backplane, also known as the hot-swap-drive backplane, is theprinted circuit board behind these bays.The hot-swap-drive backplane controls the IDs for the internal hot-swap drive bays.The following table lists the IDs for the hard disk drives and backplane that areconnected to hot-swap models.Device IDDrive bay 4 0Drive bay 5 1Drive bay 6 2Drive bay 7 3Drive bay 8 4Drive bay 9 542 System x3400 Types 7973, 7974, 7975, and 7976: User’s Guide
